Marcov Spline
Radial basis functions include the Thin Plate Spline, Natural Cubic Spline, Marcov Spline, Exponential Spline, and Rational Quadratic Spline. These methods are best for correcting local distortions. RMS values are not reported when using radial basis function methods as these methods are perfect interpolators at the control points.
The minimum number of control points required for the Marcov Spline transformation is four. The equation is of the form:
